How adorable is Jamie Oliver? I loved him when he first appeared on our TV screens as the young Naked Chef, scooting around on his Moped and cooking up a storm in his simple London pad. Since then Jamie has risen to the pinnacle of fame and fortune, but what I find so endearing about him is that he’s still just a cheeky little boy at heart. This week he instagramed this hilarious pic prompting his new series Food fight club, wearing a black mop wig and a mischievous look – a look that I bet got him into all sorts of trouble when he was growing up!

Other celebs have been busy snapping away on Instagram this week, too. Check out the gallery of our favourite star instagrammy pics!
